Sample
Embedded/polished (Fe,Mg)O melt droplet, stoichiometric Fe content 0.7 (this sample)
Processing steps
Step Chronology Date Type Process Changes
#1 before layer formation mixing mixing magnetite, metallic iron or ferrous oxalate with magnesium carbonate under inert conditions
#2 during layer formation pressure pressing the stoichiometric mixture to a pellet under inert conditions
#3 during layer formation thermal melting the pellet in an arc furnace under argon atmosphere
#4 during layer formation thermal quenching melt droplets of 5-10 mm diameter on water cooled copper plate
#5 after layer formation mechanical embedding part of the droplet in epoxide resin and polishing
